Given numbers are 645, 847, 755, 982
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 847) = 546315
GCD(645, 847) = ( 645 x 847 ) / 546315
= 645 / 847
= 645
Step2:
LCM(1, 755) = 755
GCD(1, 755) = ( 1 x 755 ) / 755
= 1 / 755
= 1
Step3:
LCM(1, 982) = 982
GCD(1, 982) = ( 1 x 982 ) / 982
= 1 / 982
= 1
So, Greatest Common Divisor of 645, 847, 755, 982 is 1
